Question

If p(a) = 0.8, p(b) = 0.7 and p(a|b) = 0.6, what is p(a and b)?

Answer 1

you may see above answer

Answer 2

Answer:

P(A∩B) is 0.42

Step-by-step explanation:

Given;

P(A) =0.8

P(B) = 0.7

P(A/B)= 0.6

As we know that,

P(A/B)= {P(A∩B)} /P(B)

0.6 = P(A∩B) / 0.7

P(A∩B) =0.6× 0.7

           =0.42
